used safety razor blades might be applied and Fig. 6 is a plan view showing the utilization of held in position for use. Such prior devices, the clamp as a pivot on which the two portions of however, have been objectionable in many ways, the handle may be swung for opening, particueither in their being complex and expensive in larly to release a blade from the magazine end. 65 construction, or being entirely too flimsy to hold As shown in the drawing, my novel and imsuch a blade properly, or to require entire disproved device comprises a pair of cooperating mememberment by the utilization of screw-driver, tallic handle or holder members 1 and 2, each or the like, when removing or placing the blade, formed with a central slot 3 in which a sliding or changing it in the holder. clamping button 5 is fitted. This clamp 5 is 70 My present invention is directed to obviate the formed with an opposite pair of clamping memdifficulties heretofore found in devices of this bers 6 and-'7 engaging the outer sides of the holdkind and to provide a novel, eflicient, sturdy, ers l and'Z and with a central stud 8 adaptedto strong, and quickly adjustable holder with ready traverse the slots 3. The members 6 and '7 may capacity for changing a blade independently of be united by forming'the stud 8 on one of the 75" any adjusting screws, screw-drivers, or the like. members, such as '7, and having a projecting por- In carrying out my invention I provide a contion 9 adapted to extend through a central reveniently formed and shaped handle member .cess in the opposite clamp 6 and headed thereon, with capacity for holding a blade at either side as clearly shown in Fig. 3.

or at the working end of the implement, and with One of the handle members, viz. 2 as here shown, means to clamp and hold the blade in position is formed with a plurality of projecting studs by the simple sliding action of a button-like mem- 12-12 and 13-13, and the opposite member 1 ber. is provided with correspondingly positioned open- Also, I provide in the end of the handle portion ings 15 15, which latterregister with the studs an enlarged recess suitable for holding a plural- 12-l2 and 13-13 when the members 1 and 2 85 I ity of spare blades.

Preferably also onone of the ment of the clamping button I am enabled to remembers, here shown as 1, I form handles 1616 lease a blade already clamped, position the same to facilitate the opening and separating of the two at either side or front of. the implement, and p r i n 1 n wh n vinar p naer p reclamp the blade or replace with a new one by Sitioning a Cutting blade 20. These blades y 90 sliding the button-like clamp member, thus quickconveniently be t u u yp f a y raz I 1y holding the tool and implement in desired blade, Which can be in'great numbersend at Working position slight expense, and afford an entremely fine out-- Also, I may similarly slide the button to reting tool- 40 lease a blade from the magazine recess or holder The Studs 12 and 13 and the cooperating recesses 15 are spaced to fit on the usual safety razor blade in the handle portion, or to move a blade into protecting. position with its edge within the imand so posltloned h the blade 20 may fluted plemm endefor carrying if desired across the studs 12-12 at theend of the implement and thereupon clamped in position or may Refemng to the drawmg luustratmg be fitted at either side across a stud 12 and 13 5 e ferred embodiment of the invention, and thereupon G1 a mm d mposifion 1 is a Plan View of my impmved holder As indicated n dotted lines in F1 1 th blade 1 Showing t blade at the end of the implement in 20 when positioned on the studs .1 5 15.is held Working 9051mm; with the cutting edge, or edges, in protected posi'e Fig. 2 1s 'a corresponding plan view showing tion- Y 105 the blade at one side, vi t right, and;i11ll5- The sliding action of the clamp 5 effects the trating in dotted line the position of the blade at locking and clamping by a simple movement of t l t o fl p t; V the slide E in the slots 3. Preferably, also, I so Fig. 3 is an enlarged cross-sectional View On form the members 1 and 2 that they will have the line 3-3 of Fig. 1; a normal spring part, as shown in Fig. 5, when no.

the clamp 5 is moved to the lowermost portion of the, slot 3, which still further facilitates the fitting and positioning of the blade in any desired location, either at the end, or the right or left of the implement end of the device.

In order to provide a convenient holder for a plurality of blades 30, as well also to provide a better handle gripping portion, I form the end of each member 1 and 2 opposite to, the implement holding memberslightly cupped: or expanded, as shown at 21 and 22 so that these portions together form a recess of considerable size to hold a substantial number of spare blades as a mag azine holder for the implement end. Partial sepe;

aration of the parts 1 and 2 and partial rotation of the same on the sliding clamp 5, when the clamp,

is in releasing position, will facilitate the extraction of an extra blade from themagazine end-and without losing, the others.

It will be appreciated that I have devised an extremely simple, eiiicient, strong, sturdy, and useful holder and handle for using detachable blades, and the quick clamping action through the sliding member 5, as well as the magazine feature, is believed to be a distinct novelty in this art and is intended to be claimed herein broadly.

I claim:

A combined blade holder and magazine carrier, comprising a pair of cooperating handle portions, having means at one end to lock and'hold a cutting blade in adjusted position at the end or side and capacity to hold a plurality of supporting cutting blades at the opposite end portion, in com bination with a sliding pivot and clamp upon whichpivot the handle portions may be rotated to facilitate removal of a spare blade from the handle: end, and the sliding action of the pivot clamp serving to look a blade in working position at the implement end.
